Embodiment Construction

[0180] Hereinafter, some embodiments of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0181] For example, expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial" that indicate relative or absolute configurations not only strictly mean such Arrangement also means a state of being relatively displaced by an angle or a distance with a tolerance or the degree to which the same function can be obtained.

[0182] For example, expressions such as "same", "equal" and "uniform" that indicate that things are in an equal state not only strictly represent an equal state, but also represent a state where there is a difference in the degree of toleranc...

Abstract

Provided is a spray drying system for drying wastewater to be dried, said spray drying system comprising: an exhaust gas introduction line that is connected to a plurality of exhaust gas ducts for flowing exhaust gas, emitted from an exhaust gas source, and that introduces the exhaust gas; and one or a plurality of spray drying devices that are connected to the exhaust gas introduction line and configured to bring the exhaust gas, introduced from the exhaust gas introduction line, into contact with the wastewater, wherein the number of the spray drying devices is smaller than the number of theexhaust gas ducts.

Description

technical field [0001] The present disclosure relates to a drying device for drying waste water generated when treating exhaust gas discharged from an exhaust gas generating source such as a boiler. Background technique [0002] Exhaust gas discharged from a boiler (exhaust gas generation source) installed in a thermal power plant or the like is purified through treatment by an exhaust gas treatment system, and then discharged into the atmosphere (outside). This exhaust gas treatment system includes the following various devices: a denitrification device for removing nitrogen oxides from the exhaust gas; an air heater for recovering the heat of the exhaust gas passing through the denitrification device; A dust collector for dust; and a desulfurization device for removing sulfur oxides in the exhaust gas after dust removal. These various devices are installed in series in the flue (pipe) connected to the boiler. As for the exhaust gas treatment system, the following exhaust ...
